Treshhold Alert Rule Template

Openhab Version ist 5.0.1.; openHAB Rules Tools [4.1.0.0;5.9.9.9]; JavaScript Scripting.

Cannot verify version of the template because when I try to create a threshold alert rule it says: “Template pending”

I am sure the error comes from the template as I watch the openhab.log when I trigger the rule manually.
